A thick haze engulfed the national capital on Thursday morning, with the air quality deteriorating to ‘hazardous’ category as Delhiites continued to burst firecrackers long after the deadline set by the Supreme Court.
On Thursday morning, Anand Vihar recorded the overall Air Quality Index AQI at 999 (hazardous) with PM2.5 level at 999 and PM10 level at 999. AQI in several parts of the Delhi and its nearby areas was similar.
The air quality started deteriorating rapidly from 7 pm on Wednesday. The AQI was 281 at 7 pm. It rose to 291 at 8 pm and further deteriorated to 294 at 9 pm and 296 at 10 pm, according to the CPCB.
The Supreme Court had allowed bursting of firecrackers from 8 pm to 10 pm only on Diwali and other festivals. It had also allowed the manufacture and sale of only “green crackers”, which have a low light and sound emission and less harmful chemicals.
The court had asked the police to ensure that banned firecrackers were not sold and said in case of any violation, the station house officer (SHO) of the police station concerned would be held personally liable and it would amount to committing contempt of court.
But despite the apex court order, there were reports of its violation from many areas long after 10 pm.
Several areas showed a spike in air pollution. Areas like Anand Vihar, ITO and Jahangirpuri recorded very high pollution levels.
Violations of the Supreme Court order were reported from Mayur Vihar Extension, Lajpat Nagar, Lutyens Delhi, IP extension, Dwarka, Noida Sector 78 among other places.
The police admitted that there were violations, adding that they would take serious legal action against those violating the apex court order.
The online indicators of the pollution monitoring stations in the city indicated “poor” and “very poor” air quality as the volume of ultra-fine particulates PM2.5 and PM10, which enter the respiratory system and manage to reach the bloodstream, sharply rose from around 8 pm.
According to the CPCB data, the 24-hour rolling average of PM2.5 and PM10 were 164 and 294 micrograms per cubic metre respectively.
The situation was similar, if not worse, in the neighbouring areas of Delhi such as Gurugram, Noida and Ghaziabad, where crackers were burst, as usual, raising question marks on the efficacy of the administration in enforcing the apex court’s ban.
A “very poor” AQI essentially means that people may suffer from respiratory illnesses on a prolonged exposure to such air. If the air quality dips further, the AQI will turn “severe”, which may trouble even those with sound health conditions and seriously affect those with ailments.
As many as 209 calls were received by the Delhi Fire Services on Diwali, including one related to a huge fire in a factory at Bawana, officials said.
